SPECIFICATION forming part of Letters Patent N0.404,582, dated June 4. 1889.

Application filed May 2, 1885. Serialll'o. 164,197. lNo modular-"- To all whom it may concern- 3e it known that I, SETH WHEELER, of the city of Albany, in the county of Albany and State of New York, have invented new and useful Improvements in Machines for Making Perforations in Paper, of which the following. is a specification; reference being had to the accompanying drawings, forming part thereof. My invention relates to a new and improved means for making a series of small perforations in paper, so that such paper can be easily separated into small pieces; lleretofore perforations have been made in paper by punching them out with the aid of dies and punches. This is slow and expensive,br-cause of the thinness of the materialthe paperoperated upon. v

In the drawings is represented a machine containing my improvements. 7

Fig. i is a longitudinal section of the cylinder over which the paper passes in being abraded. Fig. 5 is adetached view of the plates attached to the machine at each end of the said cylinder. Fig. (i is an enlarged View of the ends of the teeth against which the paper is held to be abraded. Fig. 7 is a sectional view of the friction-clutch. Fig. 8 is afront view of suchfriction-clutch with the spring-arms removed.

.be set eccentric to the cylinder a is the bed-plate of the machine, to which is bolted two standards I) Z). In the top of each of these standards is a circular hollow casting c. In these circular hollow castings c c are placed the journals 1? :7 of .the cylinder 6.

fis a shaft extending through the cylinder 0, having its journals in four plates 1 g g g, rigidly secured by set-screws [L h It It to the circular castings c c, two plates at each side of the standards I: 1', such shaft also passing through oblong openings i in each of the three yokesjjy', in order that such shaftmay On the sides of each of these yokes at k l.- are flanges, in order to have bolted thereto platesl L at opposite sides of the shaft f in one and the same plane and ext-ending lengthwise along the interior of the cylinder 8. These plates distance at each end.

rounding the larger diameter shaft fa short g has motion because of the openings or slots 0 0', through which the set-screws h it pass, so that by releasing the set-screws and turning the shaft f by means of a square f at the end of the bearing or smaller diameter f placed eccentric to thelarger diameter of the shaft f, the plate 1, being vertically slotted at g, permits the bearing f to change its position up'or down .in the making of the adjustment sidewise of the plates g g, in order to the shaft f more or less eccentric to the cylinder 0, and thus carry the teeth mm moreor less beyond the periphery of the surface of the cylinder 0 at intervals during its revolution, as hereinafter described.

The plates 1 g are to be shifted, in order to get the extent to which the tooth-plates l I shall project through the slotted openings 91 n and beyond the periphery of the cylinder c, at certain positions of the cylinder 8 when rotating relative to the abrading-roll, for the purpose of eifccting the proper abrasion of the paper.

1) is a feed-roll, having its bearings in the standards I; I), over which the paper to be perforated is fed on its way to the cylinder (4. This roll is geared to .the end of. the periphery of the cylinder 6 by the gearing 1/9)".

The shaft of the feed-roll extendsout on one Ill .side, and on it is placed a belt-wheel p. so

as to communicate motion to the l OtWl-IOll f) and cylinder 1' from the prime motor.

(I is an abradingroll journaled in the standards I) Z) opposite the cylinder '1', the body of which should be composed of emery or other abrading-surface.- The shaft of the roll also extends out at one side, and on such end is placed a belt-wheel q, to which power is to be applied from a primeunotor independentof the power supplied from the prime motor through the belt-wheel 11.

r is a roll journaled quite low dowi'r in the Each of these plates ings for the winding or receiving roll u.

standards Z; b for holding the roll of paper to be perforated.

s s are two posts on the front of the ma chine, through hearings in which passes a shaft i. To this shaft are two vertical arms t 6 In the upper ends of these arms are hear- The roll a is driven by a system of belts and pulleys in manner as follows: At the end of the shaft of the roll a is a pulley 1. At the end of the shaft t are two pulleys 2 3,rigidly connected together, and at the end of the shaft of the feed-roll is a friction-pulley. Th s friction-pulley is constructed as follows:

t is a spool rigidly connected to the end of the shaft of the feed-roll p. In place of an outer wall to this spool there is substituted a disk 5. This disk has its center cut away, so as to rest on a shoulder made in the end of the shaft of the feedaoll'p, and contains a teat or projection 6, which takes into the opening 7 of this shoulder 8.

9 is a set-screw, which passes into the threaded end of the shaft of the feed-roll p, theneck of which presses against a flange 10, from which project a number of radial spring-arms 11 11, the ends of which impinge against the outersurface of the disk 5. r

12 is a pulleybl0ek running freely on the spool 4. I

13 is a belt passing over the periphery of the pulley-block 12 and pulley 3, so as to give motion to the pulley-blocks 2 3, runningloosely on the shaft 25 when the shaft 10 is in motion, and the set-screw 9 turned inward, so that the radial spring-arms 11 11 will press the disk 5 up'against the loose pulley-block 12, and thus cause frictional contact with it of the wall of the spool 4 and the inner surface of the disk 5.

14 is a belt running from the pulley-block 2 to the pulley block 1, so that the motion given by the shaft p to the pulley-block 3 through the belt 13 will be transferred to the receiving-roll a through the pulley-blocks l '2 and the belt 14.

The object of the friction-pulley is that in case the power which is applied to theshaft of the feed-roll 1), through the medium of the belt on the pulley 1/, shall soincrease as to unduly strain the paper while it is being taken up by the receiving-roll, and thereby endanger the tearing of the paper as it is runnin g thereon fromcylinder c, the loose pulleyblock 12 will slip before the limit is reached at which the strain will tear the paper, by causing a slipping of the loose pulley-block 12 and the relaxation of the winding of the paper up onto the receiving-roll it through the operation of the belts 13 14 and the pulleys 1 2 3 4. This adjustment to counteract such strain is made by set-screw 9. (See Fig. 7.)

The operation of the receiving-roll u is such that it will yield by rcason-of the movement outward of the standards I, t" as it fills up with the perforated paper delivered to it from the cylinder 0. The standard 25 may be removed from the shaft f by unscrewing the the shaft t.

set-screw 1:, passing through the sleeve n into by be removcd,when full, from its hearings in the standards 25 t, so as to insert another roll for receiving the perforated paper.

The operation of the machine in abrading the surface of the paper so as to make lines of perforations therein is as follows, having reference more particularly. to the manufacture of paper for toilet use, although the invention is not limited to the treatment of such paper, as postage'stamps, bank-note, check, and other descriptions of paper can be also perforated with but slight modifications in the mechanism shown.

The paper intended for toilet use is placed upon the roll 'r. Its end is then drawn around the feed-roll 11 and on up between the cylinder 6 and the abrading-roll g. It then The receiving-roll it may thercpasses on, after it has been perforated by the abrading'proce'ss, to the take-up or receiving roll a. (See the three arrows at y z in Fig. 3.) On motion being given to the pulley p" the cylinder ewill be rotated in the direction of the arrows shown thereon, (see Fig. 3,) and by reason of the shaft f being set eccentric to such cylinder 6 through the adjustment of the plates 9' g the yokes j j j will cause the teeth- 'm' m, attached to. plate Z l, to alternately project through the slots n n in the cylinder 6 and beyond its periphery, as such slots are respectively opposite the surface of the abrading-roll q. The abrading-roll q is run by means of a belt over a pulley q on its shaft and 'to be operated by a pulley on the prime motor, which abrading-roll has a greater speed given to it than the cylinder e receives from the rotation of the shaft of the feed-roll through a belt on the pulley 19", thus causing the 'surface of "the abradingroll to abrade the surface of the paperas it is forced out against the periphery of such abrading-roll by means of the ends of the teeth on m. As the cylinder epasses out of the position shown in Figs. 1 and 3, the

teeth'm m are gradually withdrawn within the slots a 'n', so that the paper will run freely over the periphery of the cylinder and onto the receiving-roll a. This withdrawal of the teeth at m is due to the movement of the shaft f within the yokes jjj, its axial line and that of the cylinder 6 not being coincident, due to the adjustment of the plates g g to attain such eccentricity. The teeth on in are so adjusted before the commencement of the operation that they will just touch the surface of the periphery of the abrading-roll (1 while passing it. 'It follows that when the paper is run in between the ends of the teeth and the abrading-roll it will be abraded, thus giving lines of perforations across its surface. The ends of the teeth m m may be sharpened before running in the paper by the adjustment of the shaft f and the plates g g g g, the cylinder 6 and the abradihg-roll being run at different speeds, as

before stated.
